  • Patent number: 12242184
    Abstract: The present invention pertains to the field of nanoimprint lithography (NIL) processes and more specifically to a soft NIL process used for providing a sol-gel patterned layer on a substrate. Specifically, this process comprises a step of adjusting the solvent uptake of the sol-gel film to 10 to 50% vol., preferably between 15 and 40% vol., by varying the relative pressure of the solvent while a soft mould is applied onto the substrate coated with the sol-gel film.

  • Publication number: 20190059163
    Abstract: In order to counter heat propagation between adjacent sections of a ribbon-like printed circuit board, the sections being individually exposed to heat between opposed border lines, with printed circuit board including an electrically insulating substrate with electrically conductive pads for mounting components thereon, the adjacent sections are terminated at the opposed border lines with at least one electrically conductive borderline pad, which has a separation gap to the border line, and/or is coupled to an electrically conductive line extending on substrate between a first end at borderline pad and a second end away from borderline pad. The first end and the second end may be located at a first and at a second distances to border line, the second distance being longer than the first distance, and/or the electrically conductive line may have a narrower cross section than the first and the second ends.

  • Publication number: 20170292317
    Abstract: An active glazing system (100) includes a double glazing, with two transparent plates (1a, 1b) that together delimit an intermediate volume (2) filled with gas. The system further includes a control device (10) that is capable of producing a transition in a volatile compound present in the intermediate volume, between a dry vapor state and a supersaturated vapor state of the volatile compound. Switching processes can therefore be controlled for the double glazing, between a transparent optical state and a diffusing optical state. Such a system can be used as building or vehicle glazing, an interior partition arrangement, a projection screen, a solar diffuser, a light source diffuser, a vision blurring device, etc.

  • Publication number: 20170047485
    Abstract: A substrate for mounting electrically-powered light radiation sources, e.g. LED sources, includes a base layer of electrically-insulating material, such as PET, and a contact layer of electrically conductive material, e.g. copper. The contact layer includes a mounting area for a light radiation source having opposed anode and cathode terminals, including two portions with a gap therebetween. Therefore, the light radiation source may be mounted bridge-like across gap, with anode and cathode terminals soldered to respective soldering surfaces provided in the one and the other of said two portions of the mounting area. The latter portions include respective solder flow blocking formations including fork-shaped apertures in contact layer leaving base layer uncovered. The fork-shaped apertures have a web portion and prongs extending from web portion towards said soldering surfaces.

  • Publication number: 20170043369
    Abstract: A surface coating method includes the steps of preparing a solution containing a solvent and a material or its precursor, intended to cover a surface to be coated, which is non-volatile, film-forming and soluble or can be in suspension or dispersed in a solvent; and generating an aerosol of the solution. The method further includes generating an aerosol flow from a first end of a tube towards a second end of the tube, wherein the second end pre-determined cross-section (Se) and provided with a spray nozzle having an outlet with a cross-section (S) smaller than the cross-section (Se) of the second end of the tube, such that the ratio R1=F/S is greater than 4 metres per second. The method also includes the steps of directing the outlet of the nozzle towards the surface to be coated and spraying the aerosol onto the surface to be coated.

    Abstract: A method and a porous article are provided. In said method, a porous article which comprises a matrix material in a solid state and pores therein, is processed at least some of the pores being open to an outer surface of the article. A flowing treatment substance is applied to the outer surface of the article and into at least some of the pores. The flowing treatment substance is allowed to react with the outer surface of the article and surfaces of said at least some of the pores such that a hydrophobic coating layer is established on surfaces thereof. An excess of the flowing treatment substance is removed from the article, and the hydrophobic coating layer established on the outer surface of the article is converted into a hydrophilic coating layer.
